Letters Patent No. 110,586, dated December 27, 1870.

IMPROVEMENT IN MACHINES FOR DRESSING FENCE-PICKETS.

The Schedule' rei'enfedlto in these Letters Patent and making part of the same.

bits are attached;

Secondly, to the arrangement and construction of a sliding-frame attachment and clamping device for retaining pickets 0r other articles of wood in position revolving critters or bits and Thirdly, to certain detail construction of parts forrnf ing a pointing or cutting devicethe ent-ire arrangement and combination oi' partsforming a machine to point the ends, as well as to cut circular sides'or edges to the heads of pickets or fencepalings.

To enable those skilled in the art to make and use preparatorv to feeding said lumber to the action of .our said invention, we will nou/.more fully describe the same, referring to the accompanying- Figure l as a front elevation; to

Figure 2 asa top plan and to Figure 3 as an isometrical view of our improved pointing device. I

XVe support the operating devices of our machine upon suitable united frames A A', usually of wood or east-iron, of 'the outline as shown in thedrawing.

0n the top, as well as centrally within the -framc .part A, We arrangev vertically parallel the respective shafts B, which carry the pulleys B'. y Said shafts B rest in proper journal-bearings b on the frame A, and each of said shafts extends-say, to the center of the .frame-part A.

On the top of the frame A we have arranged the frame'attachrnent C,.`soas to freely slide inthe side lods c, connected to uprights c', secured to each end of the part-frame A'.

The sliding frame O we construct rectangular in form, having the horizontal extension-bar D andl the Lead-transom D1. v

lTo the horizontal bai-D is secured a snag, E, to which is pivot-ed the lever` E', constructed so as to form a clamp for bracing the pickets against the transom D1 and guide-rod D2, and as dearly' shown in gs.v 1 and 2.

lThe ends of cachshaft B we provide with east headblocks F, to which are attached, top and bottom, the required gauge-bits F', as shown in iig.4 1. Said bits are constructed of the various forms and shapes de-l sired, having a. slot, f, in which a suitable set-screw, f', firmly secures said bits to the cutter-heads F, in. position required.

To form a device to point the head of pickets we have pivoted'to one side of the trame-part A the handlever Gr, 'provided with a proper cutterblade, g.

Furthermore, \to the other side of said frame A we have secured in an angled position the stay-bolt H and guide-pin h, the picket being inserted between said part-s, as clearly indicated in tig. 3.

The operation ot these parts is therefore as follows: f v The required gauge-bits F' being attached in proper position. to the respective cutter-heads F, the shafts Bcarrying-said parts are' caused to revolve by means of helting passing around the pulleys B', and operated by ordinary power-source' as usual.

The operator placing the fenee-palings I, (or other articles of \vood,) to be dressed, upon the-slidingfraiue C, clamps said lumber, by means of thelevei-E, firm- A lyagainst the head-transom Dl and guide-rod D2.

The operator next causes the slide O to feed the pickets to the action-of the revolving cutter orbits F.

The edges of the pickets being thus cut to the required shape and form, the operator next disengagcs said lumber from its engagement preparatory to pointing the heads of each picket. This isaccomplished by the operator inserting the picket in an inclined position between the stay-bolt H and piu h and by means of the cutter G, as clearly shown in iig. 3.

`1t is plain, from the operation ot' our machine, that pickets andl other wooden articles may be pointed or dressed at the end .and head in the various desired forms with great expedition and accuracy, and that the principle of'eonstruction involved is simple and economical.

Having thus fully described our said invention, Vhat we claim is flhe arrangement of the cutter G, stay-bolt H, pin

h., forming a pointing device, in combination with the frame A, substantiallyas set forth In testimony' of said invention we have hereunto set our hands in presence of,-
